What is the maximum vertical distance allowed between headers when building multi-wythe masonry walls?

In building multi-wythe masonry walls, the code typically allows for a maximum vertical distance of 24 inches between headers. This distance is crucial because it ensures adequate support and structural integrity for the wall. Headers are elements that help distribute loads across the wall, and maintaining this vertical distance allows for proper load distribution and reduces the risk of structural failure, cracking, or other issues that can arise if the spacing is too great.

The regulation surrounding this maximum distance is designed to ensure that the masonry wall remains strong and capable of withstanding various stresses that may be applied to it. By adhering to this guideline, builders can create walls that are not only compliant but also durable and safe over the long term.

While the other options suggest different measurements, none align with the standard allowance of 24 inches for maximum vertical spacing between headers, emphasizing the importance of following established construction codes and practices for safety and integrity.
